public class UserDataHelper

extends java.lang.Object

This helper class assists with the logging associated with invalid input
data. A developer may want all instances of invalid input data logged to
assist with debugging whereas in production it is likely to be desirable not
to log anything for invalid data. The following settings may be used:

NOTHING: Log nothing.

DEBUG_ALL: Log all problems at DEBUG log level.

INFO_THEN_DEBUG: Log first problem at INFO log level and any further
issues in the following TBD (configurable) seconds at DEBUG level

INFO_ALL: Log all problems at INFO log level.

By default, INFO_THEN_DEBUG is used with a suppression time of 24 hours.
NOTE: This class is not completely thread-safe. When using INFO_THEN_DEBUG it
is possible that several INFO messages will be logged before dropping to
DEBUG.
